论文摘要
对于$ d \ geq 2 $尺寸中的单个自由标量字段，几乎所有统一的保形缺陷都必须是“琐碎的”，因为它们无法持有有趣的动态。唯一可能的例外是$ d \ geq 4 $中的单片缺陷和$ d \ geq 5 $的三个缺陷。作为中间结果，我们表明，$ n $点的相关函数与广义自由谱必须是广义自由理论的相关频谱。
For a single free scalar field in $d \geq 2$ dimensions, almost all the unitary conformal defects must be `trivial' in the sense that they cannot hold interesting dynamics. The only possible exceptions are monodromy defects in $d \geq 4$ and co-dimension three defects in $d \geq 5$. As an intermediate result we show that the $n$-point correlation functions of a conformal theory with a generalized free spectrum must be those of the generalized free theory.
